IBGIQ'DIING DEVICE F0132, RAILE.

To all whom it may concern Be it known that I, ALFRED A. Zrnonnn, a citizen of the United fatates, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Bonding Devices for Rails, of which the following is a specification.

This invention relates to bonding-devices for rails.

It is the common practice to attach the ends of the bond-wires to the rails and to form large loops which extend over the tie- These loops are unsupportei except at their encls anti are very objectionable on account of the liability of being broken, as in such event the signal-circuit is di ruptecl. Heretofore means have been devisecl for supporting the bond-wire loops between their ends, but either the wires are concealed for a substantial portion of their length and hence do not admit of immediate inspection, or they are connected. with the tie-plate or with the attaching-means for the tie-plate in such mannen as to interfere therewith and cause trouble, particularly between the men who have charge of the track, and the men who have charge of the In one embodiment of my invention the tie-plate has formed on its outer side one or more grooves which are extencieo. from end to end of the plate, which are made large enough toreceive the honrtwires, and said groove or grooves are so disposed as to extend under the heads of the attaching-bolts or' the washers beneath the nuts on the sttaching-holts, ancl said groove or grooves are made of a depth slightly less than the 'cliaineter of the wire so that when the wires are arranged therein they will he impinged and this affords additional electrical connection of the wires with the rails; and in another embodiment of the invention the groove or grooves are made of a depth slightly greater than the diameter of the Specification of Letters Patent.

wire, to looselyreceive the wire, encl aclmit of removal and replacement of 21 wire with out disturbing the attaching-means.

Figure 1 is a front elevation of the orijacent end-portions of a pair of rails with Y a boncl-wirc attached. thereto, the loop of which is supported by means embodying this invention. is e. front view of the tie-plate. Fig. 3 is enlarged transverse longitudinal section taken on the dotted line 3-3, Fig. 1. Fig. at is a trensverse'verticai section taken on the (iotteti line r Fig. 1. Fig. 5 is a similar transverse vertical section of a modified form of my invention.

10, 10, represent the end-portions of a pair 01 ralis; 12 the tie-p which is securecl thereto by any attechingholts i3, and 15 the hond' wire which is attached at its ends to said endporticns oi the rails. The tie-plate has formed on its outer side or face one or more grooves $9, two being here shown, which are errbenclerl from end toend of the plate. Said groove or grooves are arranged near the holes for the attaching-bolts, so that when the howl-wire is arranged therein. the usual washer ""1 the attachingbolt will extenclover the groove and thus keep the bond-wire in place in this embodiment oi? the invention. the loop of the bond-wire is supported is exposed throughout its length,- ancl hence may he easily and quickly inspectml, anol a break therein may he readily ionic.

In the form shown in 43: the groove or grooves. which are forinetl thelouter si-rle-nr face of the tie 1 depth slightly less than c wire and the heacl of the Washer thereon will electrical connection the gagenient which is of import Wire breaks between said form shown in Fig. 5, the of greater depth than. the wire, so that the wire is loos bolt.

1 claim V v A support fofhonding wires intermediate their terminal reil connections, consisting of a rail tie plate and bolts for securing the plate in rail connecting position, said plate being formed with one or more grooves in the full length of its outer surface to receive throughout the length thereof the in- 5 terr'nediate portions of the bond Wires, said grooves extending beneath the heads of the attaching bolts.

Intestimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
